The most plentiful inquisition of Hopkins and his confederates was in the years 1644, 1645 and 1646. At length there were so many persons committed to prison upon suspicion of witchcraft, that the government was compelled to take in hand the affair. The rural magistrates before whom Hopkins and his confederates brought their victims, were obliged, willingly or unwillingly, to commit them for trial. A commission was granted to the earl of Warwick and others to hold a sessions of jail-delivery against them for Essex at Chelmsford, Lord Warwick was at this time the most popular nobleman in England. He was appointed by the parliament lord high admiral during the civil war. He was much courted by the independent clergy, was shrewd, penetrating and active, and exhibited a singular mixture of pious demeanour with a vein of facetiousness and jocularity. With him was sent Dr. Calamy, the most eminent divine of the period of the Commonwealth, to see (says Baxter [224]) that no fraud was committed, or wrong done to the parties accused. It may well be doubted however whether the presence of this clergyman did not operate unfavourably to the persons suspected. He preached before the judges. It may readily be believed, considering the temper of the times, that he insisted much upon the horrible nature of the sin of witchcraft, which could expect no pardon, either in this world or the world to come. He sat on the bench with the judges, and participated in their deliberations. In the result of this inquisition sixteen persons were hanged at Yarmouth in Norfolk, fifteen at Chelmsford, and sixty at various places in the county of Suffolk. Whitlocke in his Memorials of English Affairs, under the date of 1649, speaks of many witches being apprehended about Newcastle, upon the information of a person whom he calls the Witch-finder, who, as his experiments were nearly the same, though he is not named, we may reasonably suppose to be Hopkins; and in the following year about Boston in Lincolnshire. In 1652 and 1653 the same author speaks of women in Scotland, who were put to incredible torture to extort from them a confession of what their adversaries imputed to them.
